BACKGROUND

Generally, a computer network is a digital telecommunications network which allows nodes, or components, to share resources. In computer networks, computing devices exchange data with each other using connections between nodes via various transmission media, such as via wired or wireless mediums. Computer networks can support a large number of applications and services such as access to the World Wide Web, digital video, digital audio, and shared use of application and storage servers. The applications and services are implemented via various network resources communicatively coupled to the network, such as computing and/or storage resources. The amount of data moving across a computer network may be referred to as traffic. Typically, network data in computer networks is encapsulated in network packets, which are utilized by network resources to send and receive information.

DETAILED DESCRIPTION

Various embodiments are generally directed to techniques to utilize excess resources in a cloud system, such as by enabling an auxiliary resource utilizer to use resources while they are not needed to support primary resource utilizers, for instance. Some embodiments are particularly directed to identifying and allocating the excess capacity of resources in a cloud system to auxiliary resource utilizers based on one or more policies. For example, in various embodiments described herein may provide one or more of the following features and/or functionalities. In some embodiments, utilization of a set of resources in a cloud system by one or more primary resource utilizers may be monitored. In various embodiments, excess resources in one or more of the set of resources in the cloud system, or cloud resources, may be determined based on monitoring utilization of the cloud resources by the primary resource utilizers. In many embodiments, a set of utilization policies associated with the excess resources, such as terms of use, may be retrieved. In many such embodiments, an auxiliary resource utilizer that is in compliance with the set of utilization policies may be identified and the excess resources may be allocated to the auxiliary resource utilizer. In one or more embodiments, the set of utilization policies associated with the excess resources allocated to the auxiliary resource utilizer may be enforced. These and other embodiments are described and claimed.

Some challenges facing cloud systems include an inability to identify and utilize excess cloud resources. These challenges may result from the need for redundancy and/or standby resources to support services and applications for primary resource utilizers during peak traffic times. For example, cloud systems may be designed with sufficient resources to support peak loads. However, because peak loads occur infrequently, the additional resources required to support peak loads are only needed to support primary resource utilizers for small windows of time. Adding further complexity, a cloud system may include a complex and interdependent set of resources, causing allocation of excess resources to potentially have unanticipated and/or adverse consequences on other cloud resources. These and other factors may result in cloud systems with deficient performance, excessive costs, poor utilization, and insufficient ability to provide optimal and efficient allocation of excess resources. Such limitations can drastically reduce the capabilities, usability, and applicability of the cloud system, contributing to inefficient systems with limited capabilities.

Various embodiments described herein include an excess resource manager that is able to dynamically identify and allocate excess resources in a set of cloud resources to improve resource utilization and system efficiency. In many embodiments, the excess resource manager may enable auxiliary resource utilizers to use excess resources without adversely affecting the operation of the cloud system. For example, the excess resource manager may enable the excess resources to be utilized without disrupting the ability of the excess resources to support primary resource utilizers during times of peak load. In one or more embodiments, the excess resource manager may quickly and efficiently change resource allocation among various primary and auxiliary resource utilizers. In various embodiments, the excess resource manager may identify and enforce policies associated with the utilization of excess resources. For instance, if the load generated by primary resources utilizers crosses a threshold, the excess resource manager may automatically reassign one or more excess resources from supporting auxiliary resource utilizers to supporting primary resource utilizers. In several embodiments, the excess resource manager may configure or reconfigure various cloud resources as necessary to ensure reliable operation of the cloud system despite the dynamic allocation of the resources in the cloud system.

In these and other ways the excess resource manager may enable improved control over network resources, resulting in several technical effects and advantages over conventional computer technology, including increased efficiency and improved adaptability. In various embodiments, the excess resource manager may be implemented in a practical application via one or more computing devices, and thereby provide additional and useful functionality to the one or more computing devices, resulting in more capable, better functioning, and improved computing devices. In one or more embodiments, the excess resource manager may be implemented as a set of rules that improve computer-related technology by allowing a function not previously performable by a computer that enables an improved technological result to be achieved. In one or more such embodiments, the function may include dynamically monitoring and/or controlling cloud resources to improve efficiency and utilization of the cloud resources as an improved technological result.

Various embodiments described herein may include an apparatus comprising a processor and a memory comprising instructions that, when executed by the processor, cause the processor to perform operations comprising one or more of: monitor utilization of each cloud resource in a set of cloud resources by one or more primary resource utilizers; determine excess resources in one or more cloud resources in the set of cloud resources based on the utilization of each cloud resource in the set of cloud resources; retrieve a set of utilization policies associated with the excess resources; identify an auxiliary resource utilizer that is in compliance with the set of utilization policies associated with the excess resources; and allocate the excess resources to the auxiliary resource utilizer; and enforce the set of utilization policies associated with the excess resources allocated to the auxiliary resource utilizer.

One or more embodiments described herein may include at least one non-transitory computer-readable medium comprising a set of instructions that, in response to being executed by a processor circuit, cause the processor circuit to perform one or more of: allocate a cloud resource with a capacity to one or more primary resource utilizers; monitor utilization of the cloud resource by the one or more primary resource utilizers as a first portion of the capacity of the cloud resource; determine the first portion of the capacity of the cloud resource utilized by the one or more primary resource utilizers is below a threshold portion of the capacity; identify one or more auxiliary resource utilizers in compliance with a set of utilization policies associated with the cloud resource; and reallocate a second portion of the capacity of the cloud resource from the one or more primary resource utilizers to the one or more auxiliary resource utilizers, wherein the first and second portions of capacity of the cloud resource are equal to or less than the capacity of the cloud resource.

Some embodiments described herein may include a computer-implemented method comprising one or more of: determining utilization of each cloud resource in a set of cloud resources by one or more primary resource utilizers; identifying excess resources in one or more cloud resources in the set of cloud resources based on the utilization of each cloud resource in the set of cloud resources; identifying an auxiliary resource utilizer that is in compliance with a set of utilization policies associated with the excess resources; allocating the excess resources to the auxiliary resource utilizer; and enforcing the set of utilization policies associated with the excess resources allocated to the auxiliary resource utilizer.

With general reference to notations and nomenclature used herein, one or more portions of the detailed description which follows may be presented in terms of program procedures executed on a computer or network of computers. These procedural descriptions and representations are used by those skilled in the art to most effectively convey the substances of their work to others skilled in the art. A procedure is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities.

Further, these manipulations are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. However, no such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein that form part of one or more embodiments. Rather, these operations are machine operations. Useful machines for performing operations of various embodiments include general purpose digital computers as selectively activated or configured by a computer program stored within that is written in accordance with the teachings herein, and/or include apparatus specially constructed for the required purpose. Various embodiments also relate to apparatus or systems for performing these operations. These apparatuses may be specially constructed for the required purpose or may include a general-purpose computer. The required structure for a variety of these machines will be apparent from the description given. For instance, in some embodiments, a machine may include a virtual machine implemented on a computing platform.

Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modification, equivalents, and alternatives within the scope of the claims.

FIG. 1 illustrates an embodiment of an operating environment 100 according to one or more embodiments described herein. Operating environment 100 may include a cloud system 110 in conjunction with one or more primary resource utilizers 102 and one or more auxiliary resource utilizers 104. In the illustrated embodiments, cloud system may include a system controller 105 and one or more regions 112-1, 112-2, 112-n with each region comprising a set of resources 114-1, 114-2, 114-n. The system controller 105 may include a traffic manager 106, an excess resource manager 108, and one or more utilization policies 107. In one or more embodiments described herein, the components of the system controller 105 may interoperate to enable underutilized resources in one or more of regions 112-1, 112-2, 112-n of cloud system 110 to be identified and allocated for use by one or more auxiliary resource utilizers 104 according to one or more utilization policies 107. Embodiments are not limited in this context.

In several embodiments, cloud system 110 may provide services and applications to one or more primary resource utilizers 102. In several such embodiments, the services and applications provided to the one or more primary resource utilizers 102 may be implemented via one or more sets of cloud resources. For example, cloud system 110 may include multiple sets of cloud resources divided into regions (e.g., resource set 114-1 in region 112-1, resource set 114-2 in region 112-2, and resource set 114-n in region 112-n. In some embodiments, various cloud resource may have excess capacity to provide support at the time of peak load and/or resource failure. For example, services and/or applications implemented by cloud resources may be duplicated in multiple regions to provide redundancy or failover. In some such examples, the resources that provide the redundancy or failover may include excess resources when the redundancy or failover resources are standing by.

In many embodiments described herein, the system controller 105 and/or one or more components thereof (e.g., traffic manager 106 and/or excess resource manager 108) may identify and dynamically allocate excess resources in cloud system 110 for use by one or more auxiliary resources utilizers 104. In many such embodiments, the system controller 105 and/or one or more components thereof (e.g., excess resource manager 108) may identify and dynamically allocate excess resources in cloud system 110 for use by one or more auxiliary resources utilizers 104 according to one or more utilization policies 107. In one or more embodiments, primary resource utilizers 102 may include higher priority users while auxiliary resource utilizers 104 may include lower priority users. For example, primary resource utilizers 102 may include customers utilizing the resources for applications and/or services provided by a business and auxiliary resource utilizers 104 may include employees of the company or third parties that utilize the resources for one or more of testing, quality assurance, integration, simulations, developing, research, or the like.

In several embodiments, excess resources may be allocated to auxiliary resource utilizers 104 while still serving the redundancy or failover role. In several such embodiments, the excess resources may automatically be reallocated to one or more primary resources utilizers 102 on an on-demand basis. For example, traffic manager 106 may monitor utilization of the resources and enable excess resource manager 108 to determine when and/or who to allocate excess resources to. In some embodiments, traffic manager 106 and/or excess resource manager 108 may be implemented by the resources in cloud system 110. In various embodiments, traffic manager 106 and/or excess resource manager 108 may be separate from cloud system 110.

In various embodiments, the resources of cloud system 110 (e.g., resources 114-1, 114-2, 114-n) may refer to a pool of hardware that is utilized to provide computational or data services to an entity (e.g., a company) without the entity having physical access or control over the hardware providing the computational or data services. For example, resources 114-1, 114-2, 114-n may include computational or data services utilized (e.g., under a rental agreement) by the entity independent of the underlying hardware. As previously mentioned, the resources of cloud system 110, the cloud resources, may be divided into one or more regions 112-1, 112-2, 112-n. In several embodiments, each of the one or more regions 112-1, 112-2, 112-n may include independent pools of hardware that are utilized to provide computational or data services to the entity (e.g., resources 114-1, 114-2, 114-n).

FIG. 2 illustrates exemplary aspects of a resource utilization monitor 220 in environment 200 according to one or more embodiments described herein. In environment 200, cloud system 110 may include resource utilization monitor 220 and one or more regions 112-1, 112-2, 112-n with resource sets 114-1, 114-2, 114-n. In some embodiments, resource utilization monitor 220 may be included in traffic manager 106 and/or excess resource manager 108. In one or more embodiments described herein, resource utilization monitor 220 may monitor the utilization of resources in each of one or more regions (e.g., region 112-1, 112-2, 112-n) in cloud system 110. In one or more such embodiments, monitoring the utilization of resources may enable excess capacity to be identified to facilitate allocation of excess capacity to auxiliary resource utilizers. Embodiments are not limited in this context.

In the illustrated embodiment, the resources 114-1 of region 112-1 may include one or more compute instances 230-1, 230-2, 230-n, the resources 114-2 of region 112-2 may include one or more compute instances 232-1, 232-2, 232-n, and the resources 114-n of region 112-n may include one or more compute instances 234-1, 234-2, 234-n. It will be appreciated that each of the one or more regions 112-1, 112-2, 112-n in cloud system 110 may include different or additional resources than those illustrated in FIG. 2. For example, the resources of cloud system 110 may include any component utilized by or included in cloud system 110, such as a data storage components or network infrastructure components.

In environment 200, resource utilization monitor 220 may include region resources 222-1 with one or more compute instance utilizations 224-1, 224-2, 224-n corresponding to the one or more computer instances 230-1, 230-2, 230-n in region 112-1 of cloud system 110, region resources 222-2 with one or more compute instance utilizations 226-1, 226-2, 226-n corresponding to the one or more computer instances 232-1, 232-2, 232-n in region 112-2 of cloud system 110, and region resources 222-n with one or more compute instance utilizations 228-1, 228-2, 228-n corresponding to the one or more computer instances 234-1, 234-2, 234-n in region 112-n of cloud system 110.

In various embodiments, resource utilization monitor 220 may track the utilization of each resource in each region that is allowed to be allocated to auxiliary resource utilizers. In some embodiments, the resources allowed to be allocated to auxiliary resource utilizers may be included in utilization policies 107. In many embodiments, resource utilization monitor 220 may include one or more region resources 222-1, 222-2, 222-n. In many such embodiments, the one or more region resources 222-1, 222-2, 222-n may correspond to regions of resources in cloud system 110. In various embodiments, each of the one or more region resources 222-1, 222-2, 222-n may be used to track the utilization of resources in the corresponding region. For instance, compute instance utilization 224-1 may include the utilization of compute instance 230-1 of region 112-1 and computer instance utilization 228-n may include the utilization of computer instance 234-n of region 112-n.

In some embodiments, resource utilization monitor 220 may additionally, or alternatively, monitor traffic flow in cloud system 110. For example, resource utilization monitor 220 may monitor traffic flow to and from each of regions 112-1, 112-2, 112-n. In some examples, resource utilization monitor 220 may monitor traffic flow to and from each compute instance in cloud system 110. In one or more embodiments, traffic flow may provide indications of pending resource utilization. In various embodiments, resource utilization monitor 220 may monitor types of traffic flowing to and/or from various components of cloud system 110. In various such embodiments, specific traffic types may be routed to excess resources. For instance, traffic may include video traffic and application program interface (API) traffic. In such instances, video traffic may be rerouted to excess resources to ensure the quality of service (QoS) is maintained with respect to the API traffic. In one or more embodiments, identification of excess resources and/or determining how, when, and/or where to allocate excess resources may be based at least in part on the parameters of components in cloud system 110 that are tracked by resource utilization monitor 220.

FIG. 3 illustrates exemplary aspects of an excess resource manager 108 in environment 300 according to one or more embodiments described herein. Environment 300 may include one or more auxiliary resource utilizers 104-1, 104-2, 104-n, excess resource manager 108 with excess resource identifier 336 and excess resources allocator 338, traffic manager 106 with resource utilization monitor 220, utilization policies 107, and one or more regions 112-1, 112-2, 112-n with corresponding sets of resources 114-1, 114-2, 114-n. In one or more embodiments described herein, excess resource manager 108 may identify and allocate one or more resources, or portions thereof, in regions 112-1, 112-2, 112-n to one or more auxiliary resource utilizers 104-1, 104-2, 104-n. Embodiments are not limited in this context.

In some embodiments, the excess resource identifier 336 of excess resource manager 108 may identify excess resources to allocate to one or more auxiliary resource utilizers based on utilization of the resources monitored by resource utilization monitor 220 and one or more utilization policies 107. For example, resource utilization monitor 220 may indicate that a compute instance in region 112-2 is not utilizing 40% of its capacity. In such examples, excess resource identifier 336 may determine that any excess capacity exceeding 20% of the compute instance in region 112-2 may be allocated to auxiliary resource utilizers based on utilization policies 107. In several embodiments, the excess resource identifier may retrieve a set of utilization policies associated with identified excess resources. In several such embodiments, the set of utilization policies associated with identified excess resources may be used to determine one or more auxiliary resource utilizers to which the excess resource may be allocated.

More generally, utilization policies 107 may include one or more rules associated with the use of resources by auxiliary resource utilizers. In various embodiments, utilization policies 107 may include rules associated with any component, or operation parameters thereof, that may impact the utilization of an associated resource. For example, utilization policies 107 may include characteristics of auxiliary resource utilizers or characteristics associated with the use of the excess resources that are required for use of excess resources (e.g., use by auxiliary resource utilizers may be interrupted without warning. In another example, utilization policies 107 may include time periods that excess resources are available (e.g., low traffic times). In yet another example, utilization policies 107 may include maximum utilization of the resource with excess capacity or maximum utilization of corresponding resources (e.g., resources that the excess resource provides failover for). In some such examples, when utilization of the resource with excess capacity or utilization of corresponding resources exceeds a threshold, the associated resources allocated to auxiliary resources utilizers may be automatically reallocated to primary resource utilizers.

In one or more embodiments, excess resource identifier 336 may identify one or more auxiliary resource utilizers that comply with and/or have consented to one or more utilization policies associated with identified excess resources. In one or more such embodiments, this may ensure that any resources allocated to auxiliary resource utilizers can be reclaimed for utilization by primary resource utilizers promptly. For instance, resources may need to be reallocated to primary resource utilizers to provide failover without interrupting services or applications provided to the primary resource utilizers. In some embodiments, the utilization policies 107 may limit an amount of reconfiguring of the excess resources for use by the auxiliary resource utilizers. In many embodiments, utilization policies 107 may require the auxiliary resource utilizers to generate and/or utilize the same type of traffic as associated with the primary resource utilizes.

In various embodiments, excess resource allocator 338 may allocate excess resources to an auxiliary resource utilizer based on indications from excess resource identifier 336. In various such embodiments, excess resource allocator 338 may configure the excess resources for use by the auxiliary resource utilizer. In some embodiments, excess resource allocator 338 may enforce one or more of the utilization policies 107 on the user of the excess resources by one or more auxiliary resource utilizers. In many embodiments, excess resource allocator 338 may reallocate and/or reconfigure excess resources allocated to auxiliary resource utilizers based on a violation of a utilization policy. For example, excess resource allocator 338 may reallocate and/or reconfigure excess resources allocated to auxiliary resource utilizers based on traffic and/or load associated with primary resource utilizers crossing a threshold.

FIGS. 4A and 4B illustrate an exemplary processing flow of an excess resource manager 408 in environments 400A, 400B according to one or more embodiments described herein. Environment 400A may include one or more primary resource utilizers 402, excess resource manager 408, an east region 412-1 with compute instances 430-1, 430-2, 430-3, 430-4, 430-5, and a west region 412-2 with compute instances 432-1, 432-2, 432-3, 432-4, 432-5. Environment 400B may include an auxiliary resource utilizers 404 in addition to the components of environment 400A. In environment 400A, excess resource manager 408 may identify one or more excess resources based on traffic flow and/or resource utilization of the compute instances in east region 412-1 and west region 412-2. In environment 400B, excess resource manager 408 may allocate the one or more excess resources to auxiliary resource utilizer 404. Embodiments are not limited in this context.

Referring to FIG. 4A, excess resource manager 408 may determine traffic flow and resource utilization associated with each computer instance in east region 412-1 and west region 412-2. As shown in the illustrated embodiment, 100% of the traffic from primary resource utilizers 402 may be routed to the east region 412-1 and the traffic may be divided evenly between compute instances 430-1, 430-2, 430-3, 430-4, 430-5 such that each compute instance in east region 412-1 receives 20% of the traffic flow. In various embodiments, the 20% traffic flow to each compute instance in east region 412-1 may result in 80% resource utilization of the corresponding resources to process a respective traffic load. It will be appreciated that traffic loads may vary with time with higher traffic loads corresponding to higher resource utilization. Compute instance 430-1 may include traffic flow 440-1 of 20% and resource utilization 442-1 of 80%, compute instance 430-2 may include traffic flow 440-2 of 20% and resource utilization 442-2 of 80%, compute instance 430-3 may include traffic flow 440-3 of 20% and resource utilization 442-3 of 80%, compute instance 430-4 may include traffic flow 440-4 of 20% and resource utilization 442-4 of 80%, and compute instance 430-5 may include traffic flow 440-5 of 20% and resource utilization 442-5 of 80%, In one or more embodiments, these values may be determined by resource utilization monitor 220.

Further, west region 412-2 may receive no traffic from primary resource utilizers 402. For example, west region 412-2 may provide failover and/or dark instances for east region 412-1. In many embodiments, west region 412-2 may receive a minimal amount of traffic flow and/or resource utilization (e.g., <5%) to ensure proper operations and readiness of the resources in the region. In the illustrated embodiments, compute instance 432-1 may include traffic flow 444-1 of 0% and resource utilization 446-1 of 0%, compute instance 432-2 may include traffic flow 444-2 of 0% and resource utilization 446-2 of 0%, compute instance 432-3 may include traffic flow 444-3 of 00% and resource utilization 446-3 of 0%, compute instance 432-4 may include traffic flow 444-4 of 0% and resource utilization 446-4 of 0%, and compute instance 432-5 may include traffic flow 444-5 of 0% and resource utilization 446-5 of 0%, In one or more embodiments, these values may be determined by resource utilization monitor 220 based on log files and/or traffic sampling.

In many embodiments, in environment 400A, excess resource manager 408 may identify, in the east region 412-1 and/or the west region 412-2, excess resources not actively being used by primary resource utilizer 402, such as the compute instances 432 in region 412-2. Moving to FIG. 4B, in environment 400B, excess resource manager 408 may allocate excess resources identified in the east region 412-1 and/or the west region 412-2 for use by auxiliary resource utilizer 404. In various embodiments, excess resource manager 408 may allocate these excess resource based on and/or in compliance with one or more utilization policies 107. As shown in the illustrated embodiment, 100% of the traffic from the primary resource utilizers 402 is still being routed to the east region 412-1 and 10% of the traffic from the secondary resource utilizers 404 is being routed to excess resources in the east region 412-1. This traffic may be divided evenly between compute instances 430-1, 430-2, 430-3, 430-4, 430-5 such that each compute instance in east region 412-1 receives 22% of the traffic flow (20% from primary resource utilizer 402 and 2% from secondary resource utilizer 404). As previously discussed, the 20% traffic flow to each compute instance in east region 412-1 from primary resource utilizer 402 can result in 80% resource utilization of the corresponding resources for a respective primary resource utilizer 402 load. Further, the 2% traffic flow to each compute instance in the east region 412-1 from auxiliary resource utilizer 402 can result in 8% resource utilization of the corresponding resource for a respective auxiliary resource utilizer 404 load.

Accordingly, compute instance 430-1 may include traffic flow 440-1 of 22% and resource utilization 442-1 of 88%, compute instance 430-2 may include traffic flow 440-2 of 22% and resource utilization 442-2 of 88%, compute instance 430-3 may include traffic flow 440-3 of 22% and resource utilization 442-3 of 88%, compute instance 430-4 may include traffic flow 440-4 of 22% and resource utilization 442-4 of 88%, and compute instance 430-5 may include traffic flow 440-5 of 22% and resource utilization 442-5 of 88%. In one or more embodiments, these values may be determined by resource utilization monitor 220.

Further, 90% of the traffic from auxiliary resource utilizers 404 is being directed to west region 412-2 while the west region 412-2 still receives no traffic from primary resource utilizers 402. For example, west region 412-2 may provide failover and/or dark instances for east region 412-1. In many embodiments, west region 412-2 may receive a minimal amount of traffic flow and/or resource utilization (e.g., <5%) to ensure proper operations and readiness of the resources in the region. As shown in the illustrated embodiment, 90% of the traffic from auxiliary resource utilizer 404 may be routed to the west region 412-2 and the traffic may be divided evenly between compute instances 432-1, 432-2, 432-3, 432-4, 432-5 such that each compute instance in west region 412-2 receives 18% of the traffic flow from auxiliary resource utilizer 404.

In various embodiments, the 18% traffic flow to each compute instance in west region 412-2 may result in 72% resource utilization of the corresponding resources to process a respective traffic load from auxiliary resource utilizer 404. It will be appreciated that traffic loads may vary with time with higher traffic loads corresponding to higher resource utilization.
